Intraspecific plant-soil feedbacks alter root traits in a perennial grass.

ABSTRACT: Drought is a common stressor faced by plants and their associated microbiomes. Projected climate data point toward an increase in the severity and frequency of extreme precipitation events, such as drought. Previous research has shown that long-term exposure to drought can shape plants' genomes, resulting in genetic variation for drought tolerance. We hypothesized that these genetic changes also affect patterns of microbial colonization in the rhizosphere, potentially feeding back to influence plant drought responses. Here, we tested 33 rhizosphere soils conditioned by 33 genotypes of Tripsacum dactyloides (eastern gamagrass) that originated from native populations across a precipitation gradient in the southern plains of the United States. We used these 33 rhizosphere soils as inoc
